Abstract
This invention relates to a radio communication terminal having a detachable memory for storing private information and, more particularly, to a terminal designed to manage the private information stored in a memory in the terminal by using a detachable memory. The identification number of the detachable memory mounted in the radio communication terminal in the previous operation is stored in the terminal. In using the radio communication terminal the next time, if the identification number of the detachable memory mounted in the terminal does not coincide with the previous identification number, the private information stored in the memory in the terminal is cleared. In addition, the identification number of a permitted detachable memory is stored in the memory in the terminal to inhibit the use of a memory having an identification number other than the above identification number. When the detachable memory is detached from the terminal, the private information is transferred to the detachable memory, and the memory in the terminal is cleared. By notifying the contents of the detachable memory at a predetermined timing, recognition of the detachable memory is facilitated to reduce operation errors.
